Derrick Pitts, Hon.D
For many Philadelphians, Derrick Pitts is The Franklin Institute. Since 1978, Derrick has been teaching us to look up—and to wonder about what we see up there.

We all know that Derrick is an excellent “teacher.” What’s made him famous in Philadelphia is his ability to help everyone appreciate the universe as he sees it—not a watered-down sketch of the universe, but a rich, deep, complex version with human connections that everyone can understand at some level.
Derrick is currently the Chief Astronomer and Director of the Fels Planetarium at The Franklin Institute. He’s also been a NASA Solar System Ambassador since 2009 and serves as the “Astrobiology Ambassador” for the NASA/MIRS/UNCF Special Program Corporation’s Astrobiology Partnership Program. One of his newest honors is an appointment to the outreach advisory board for the world’s largest telescope, the new Thirty-Meter-Telescope at Mauna Kea in Hawaii.
He appears regularly in the media as a science content expert including appearances on the “Colbert Report” on Comedy Central and “The Late, Late Show with Craig Ferguson” on CBS. For more than two decades, Derrick has hosted award-winning astronomy radio programs for Philadelphia’s two public radio stations and created signature astronomy television programming for PBS. One of the highlights of Derrick’s career was meeting President Obama and his family when he was invited to participate in the first-ever White House Star Party.
Derrick has received numerous awards including an honorary Doctor of Science Degree from La Salle University, and serves on the Board of Trustees for his alma mater St. Lawrence University. His twitter handle is @CoolAstronomer and his motto is “Eat, breathe, do science. Sleep later.”

Summer’s Best Meteors – The Perseids, 2022!
The summer’s premiere astronomical event, the Perseid meteor shower, runs from late July through late August, peaking around mid-August. Meteors are sand-grained-sized particles of space rock typically “melted” out of the icy nucleus of a comet. The melting occurs when the comet passes near the sun during its orbit around the solar system. The meteors are usually distributed along the orbital path of the comet and fall into the Earth’s atmosphere when we pass through the comet’s path. The comet associated with the Perseids is Comet Swift-Tuttle, first identified in 1862.

How to Measure a Supermoon
If you’re looking to up your dose of lunar light, tonight’s the night to get a full charge. This month’s full moon occurs July 13 at 2:38p ET. More importantly, it occurs on the day of this year’s ultimate Supermoon. Of all the monthly lunar perigees this year, the July 13 perigee is the closest of the whole year. I guess we can call it a super Supermoon!

How to Read the First James Webb Space Telescope Image
Image source: NASA, ESA, CSA, STScI
This first image from James Webb Space Telescope was released July 11. The Webb science and engineering team was recognized for extraordinary work but not much was said about the image itself, except that it shows some of the oldest light ever seen by humans. Let’s go further toward understanding what the image actually shows. Here’s how to interpret this first JWST ultra-deep field image:
What we see at first glance are bright stars, some small spiral galaxies, and lots of smaller blobs ranging in color from tan to red.

An Update on the Artemis 1 Mission to the Moon
NASA’s next expeditions to the Moon took a step closer to reality when the Space Launch System (SLS) rocket passed its final dress rehearsal tests in late June.

Happy Winter Solstice!
For this second week of December, the northern half of the planet experiences its earliest sunsets for the year. We’re used to the Winter Solstice - December 21 - being thought of as the “shortest day of the year” but it’s just one of a trio of days that work together to set the astronomical framework for the winter season.

What is the Perseid Meteor Shower?
Meteors are sand-grained-sized particles typically “melted” out of the icy nucleus of a comet as it passes near the sun during its orbit around the solar system. The meteors are usually distributed along the orbital path of the comet and fall into the Earth’s atmosphere when the Earth passes through the comet’s path. The comet associated with the Perseids is Comet Swift-Tuttle, first identified in 1862. It has an orbital period of about 120 years and was last seen in 1995.
